Abstract: The 1964 coup was a political event that deeply affected the society and the Brazilian economy, implementing a dictatorship that committed the deepening of democracy recorded in early 1960. Our object of study is the analysis of Paraná at this juncture. We understand that before 1964 there was a democracy that watching the rise of social movements in politics and at the same time lived with the result of political instability successive subsequent legitimacy crisis at the end of the Estado Novo dictatorship. This scenario has been modified from April 1964 with the installation of a military dictatorship that promoted a series of outrages against the current Constitution and against political opponents. This context reflects the local level of Paraná policy. We start from the idea that the "political field" Paranaense in 1964 pre-coup period has changed considerably since the 1964 coup and the publication of Institutional Act No. 2, which established bipartisanship. Such changes have deepened with the publication of Institutional Act No. 5. This Dissertation uses literature review, analysis of biographical partner trajectories of political agents, to provide input in the work of Pierre Bourdieu and journalistic sources, in this case, the "Diary of Parana" to understand how the "political field" Paranaense was organized in the context of the 1964 coup, temporally cut between the years 1960 and 1969, focusing on the years 1963, 1964 and 1965, characterized by the polarization of the political debate.
